Hull Surveys Rev 1.2

Revision 1.2 - January 2002
Are you aware of what
SAMSA and the various
Regulations require of you?
The various Acts and regulations place the onus on the owner and in some cases the master as
well, to ENSURE that the vessel and the crew comply with the requirements of the regulations at
all times.
The SAMSA surveyors do NOT replace the owners and crew in matters of safety and their main
function is to ensure that the owner, master and crew are in fact making reasonable efforts to
apply regulations and maintain safety standards.
To assist vessel owner/owners representative to manage safety aboard and to demonstrate that
management is playing its part, the following checklist has been compiled for your assistance
and guidance. (Please note that it is not a complete list but covers the main issues.)
THE SURVEYOR WILL REQUEST A COMPLETED FORM FROM THE
OWNER/OWNERS REPRESENTATIVE BEFORE, OR AT THE VERY LATEST, AT
THE SURVEY!
Failure to do so is understood to mean that management has not applied themselves to safety
management unless they are able to produce a similar initiative on their part, and the surveyor
has been instructed to terminate the audit/survey..
Owner/Owners Representative Declaration:
I, owner/ responsible person of the vessel ............................................ have read have read
and completed this checklist in preparation for the vessel’s Hull Survey.

IMPORTANT NOTICE - PLEASE READ AND TAKE NOTE !!!
Owners/operators are advised that SAMSA regards the non-provision of safe access to vessels in a serious light. This
requirement is for all persons requiring access to vessels (not just surveyors). If inadequate accesses are found,
14
SAMSA surveyors have instructions to issue a “prohibition order” requiring that all work on board be halted and
access to the vessel be denied until access is provided to the satisfaction of the surveyor.
SAFE ACCESS
SAFE ACCESS
MOS regulation 21 &
Chapter 3 of the Code of
Safe Working Practice
for Fishing Vessels or
Code of Safe Working
Practice for Merchant
Seaman
Various options are open to the owner/operator depending on the location of
the vessel.
Guidance is provided in the Maritime Occupational Safety (MOS)
Regulations, 1994 and various Codes.
Copies of the Maritime Occupational Regulations and the Code of Safe
Working Practice for Fisherman are available at the SAMSA office nearest
to you.
DOCUMENTATION
HULL
CERTIFICATE
(Regulation 139,
181&193)
HULL THICKNESS
TESTS
A valid “DRY DOCKING CERTIFICATE” or “CARGO SHIP SAFETY
CONSTRUCTION CERTIFICATE” (Convention vessels) must be on
board.
( Regulation 181)
For steel vessels, a record of hull thickness tests must be maintained. Hull
thickness tests must be carried out 10 years after the vessels construction and
thereafter every 6 years.
ANCHOR AND
ANCHOR CHAIN
CERTIFICATES
A record of the vessel’s anchors ‘weights and the anchor chain’s original
diameter must be maintained on board. Anchors weighing more than 75kg
and anchor chain of 12mm diameter or more require test certificates.
(Regulation 168)
DRAWINGS
(Regulation 149)
CLEARANCES
With the exceptionthe owners of old wooden fishing vessels < 24m, the
owner/operator should be in possession of the following drawings which the
surveyor may require to sight:
- Midship section drawing.
- Shell expansion drawing or information on the original
thickness of the shell plating (Steel vessels only).
- Shaft and Rudder stock drawings if the vessels size renders
it necessary.
(Regulation 184&186)
Records of shaft and rudder stock clearances (if necessary) should be
maintained on board.
LUB/OIL
CONSUMPTION
Records of lubrication oil or grease consumption of the shaft and rudder
stock (if necessary) should be maintained on board.
(Regulation 184&186)
SURVEYS
SURVEYS
Convention vessels, requiring a Cargo Safety Construction certificate are
(Regulations 139, 181,
24
182 & 183)
required to be dry-docked every two years. All other vessels are required to
be dry docked annually for a hull survey, except as been allowed by Marine
Circular 23 of 1999.
HULL FITTINGS
All suction and discharge pipes passing through the hull, below the
weather-deck, are to be fitted with accessible isolating valves located as
close to the hull as possible (Not applicable for pump discharges of < 38 mm
located above the load waterline and keel cooling systems). These valves
must be dismantled every 2 years, at the Hull Survey, and will be tested in
place by the surveyor on alternate years.
(Regulation 158)
(Regulation 139)
Note - The hull fittings of Convention vessels are only required to be
dismantled every 4 years.
TANKS
The surveyor may require that tanks forming part of the hull structure be
surveyed internally or pressure tested if it is considered necessary.
(Regulation 181)
SHAFT(S)
(Regulation 181 - 183 &
M-Circular 23 of 1999)
-
Water lubricated Steel shafts are to be drawn every 2 years.
Water lubricated Stainless Steel or Bronze shafts
- Single screw: To be drawn every 3 years provided that this interval
may be extended to 4 years if the vessel is on a 2 year dry-dock
cycle.
- Twin screw: Both to be drawn every 4 years or one every 2 years.
- Oil or Grease lubricated (Fixed or C.P.P.) shafts may be drawn at a
maximum of 6 yearly intervals subject to the owner providing:
- An independent analysis of the stern tube lubricating oil taken
annually for the first 4 years and at 6 monthly intervals thereafter.
- A check of the shaft wear-down at each dry docking.
- Log book evidence of lube oil/grease consumption.
- Intervals for controllable pitch propeller shafts (CPP) may be extended
beyond 6 years if the requisite records are maintained and
manufacturers or the classification society (to which the vessel
belongs) requirements
allow such extension.
Note - A surveyor may require that a shaft be drawn for inspection at any
time if it is considered necessary.
ANCHORS,
CABLES & CHAIN
(Regulation 187)
EXTENSIONS
(M-Circular 23 of 1999)
- The anchors, cable, windlass, and steering chain (if any) of a vessel will be
examined annually by the surveyor.
- Anchor cables must be ranged for inspection 8 years after the
construction of the vessel and thereafter every 4 years.
- At the time of ranging the anchor cables, the chain locker is to be opened
for inspection by the surveyor.
A 12 month extension for docking may be granted, at the time of the annual
dry-docking, for steel and GRP vessels subject to:
- A written application to SAMSA prior to the hull survey.
- The provision of a 2-year paint scheme.
- The provision of satisfactory hull thickness test results.
If the owner/operator is unable to dry-dock a vessel before the expiry date
shown on the vessels certificate, SAMSA may extend the certificate
provided that:
- A written application for the extension is made prior to the
34
expiry date indicated on the certificate; and,
- Satisfactory proof of an intended dry-docking date is provided.

(Regulation 185)
NOTES
- The surveyor should be called to the vessel after the hull has be
cleaned down but not painted.
- Valve and/or Sea Chest gratings must have been removed.
- The owner should ensure that, as far as is practicable, internal access
to the hull is possible.
- The surveyor may require that internal access to any part of the hull
be provided to allow evaluation of frames, plating, bulkheads, etc.
- If sea cocks are removed leaving the valve bodies on the vessel, it
must be ensured that the valve bodies are accessible for the survey.
- When Sea cocks are dismantled for inspection, they are to be
presented to the surveyor in a clean and refurbished condition.
SHAFT(S)
- The shaft must be cleaned or blasted before the inspection.
- If possible, the shaft should be checked for straightness in a lathe.
- NDT (dye penetrant or magnetic particle) of the key-ways and other
high risk areas must be carried out and witnessed by the surveyor.
- “Blueing” of the shaft tapers to prove the propeller and coupling fit
must be carried out and witnessed by the surveyor. The “blue” is to
be taken with the key in the key-way and the coupling or propeller
tightened onto the taper.
(Regulation 184)
TANKS
(Regulation 181)
(MOS Reg 27)
-
If a surveyor requires a tank to be pressure tested, the tank must be
tested to a head of 2.4 metres or to the light water line, whichever
is the greatest.
- If the surveyor requires an internal inspection of a tank, the tank
must be clean, adequately ventilated and “gas free” for the survey.
