VESTIGO PETROLEUM SDN. BHD. (hereinafter referred to as “COMPANY”) has the
intention to demobilise FSU Nautica Muar from Bentara Field to Johor. Bentara Field located
approximately 130 km offshore Bintulu, Sarawak.
1.2
Overview Of The Development
The Bentara Field is located 130 km North-West offshore Bintulu, Sarawak and lies in water
depth of about 64 meters. Bentara Field has been annexed to the SK315 PSC with Vestigo
Petroleum Sdn Bhd (VPSB) as the operator of the Production Sharing Contract (PSC) and is
responsible for its development.
1.3
Document Purpose
The purpose of this document is to analyze the minimum Bollard Pull (BP) required to
demobilize the Floating Storage Unit (FSU) Nautica Muar from Bentara field, offshore
Bintulu, Sarawak to Johor Port, Johor West Malaysia.
MOSES software is used to simulate towing operation and compute the minimum Effective
Bollard Pull required.

Towline Details
The tow vessel is fitted with tow drum with maximum capacity of 2000 m x ∅70 mm wire.
However, for MOSES simulation purpose DNV guideline refer [1], is used for determining
the minimum deployable towline length.
For BP > 100MT, the minimum required towline breaking load is 2 x BP.
As specified in DNV guideline section 11.13.4.1, refer [1]:

The wave periods considered was based on the Noble Denton Guidelines for Marine
Transportations, whereby the peak period (Tp) for the sea-state considered is varied
between the equations below:13Hs  Tp 
30Hs
This method conservatively assumes that all periods within the mentioned range are
equally probable. This report has assumed peak period (Tp) = 8.5 sec.
5.7
Tug Efficiency
As stipulated in the DNV guideline in section 11.12.2.10, refer [1], tug efficiency is subject to
few parameters such as tug size, tug configuration and towing seastate. The tug efficiency
can be estimated using the following formula:
Te = 80 – (18 – 0.0417 x LOA x sqrt (BP – 20)) x (Hs – 1) %
where
LOA
= towing vessel length overall in metres (using 45 for LOAs > 45 m)
BP
= Static continuous bollard pull in tonnes (with BP > 20 tonnes & 100
for BP >100 tonnes)
Hs
= significant wave height (with 1 < Hs < 5).
The tug efficiency estimated form the above equation as follows:
Te
= 80 – (18 – 0.0417 x 45 x sqrt (100 – 20)) x (Hs – 1) %
= 80 – (18 – 0.0417 x 45 x sqrt (100 – 20)) x (3.5 – 1) %
= 76.96 %
However, as a conservative approach, 75% tug efficiency is considered in the bollard pull
calculations.

Assumptions made for deriving the minimum Bollard Pull required for towing simulation
are mentioned below:







Analyses are performed based on the relative velocity of water particles acting on the
FSU i.e., the sum of towing speed and current speed.
Windage area of FSU is calculated automatically using MOSES.
Wind loading calculations are based on API
Wave, wind and current directions are assumed to be collinear and acting against towing
direction of the FSU (180 deg)
Results obtained from MOSES are the Effective Bollard Pull (EBP) which is excludes tug
efficiency losses.
Current velocity is assumed constant over water depth.
The towline connected to the tugboat is modelled as a fixed point.
Figure 6 – Towing Simulation
6.2
Analysis Methodology
FPU vessel 3D model is generated using MOSES as per respective stability booklet and
General Arrangement drawing, refer [5] and [6] respectively.
MOSES compute hydrodynamic pressure data at the towing draft displacement using 3D
diffraction theory. All the hydrodynamic pressure data (added mass, damping) is then
converted in the time domain using Fourier series.
