Naval Architectural Projects
BRL's core naval architecture and ship design consultancy services encompass expert advice and analysis across the following areas:
Stability
Including intact and damage stability using probabilistic and deterministic methods; lightship and inclining surveys; and onboard stability software.
Vessel Motions and Seakeeping
Including assessments and predictions of vessel operability and dynamic positioning (DP) performance.
Ship Resistance and Powering
Analysis and optimisation of hull form resistance, propulsion system selection, and powering requirements.
Launching and Docking
Detailed engineering support for vessel launch operations, dry-docking procedures, and related marine activities.
Docking Calculations
Vessel — Far Sword
Scope — Comprehensive docking calculations including structural analysis of the docking cradle, assessment of keel block arrangement and bearing pressures, and design of cradle modifications to withstand increased operational loads. Included preparation of full docking plans and load distribution drawings for classification society approval.
Intact and Damage Stability
Vessel — Pacific Rapier
Scope — Preparation of a fully revised intact and damage stability book following significant vessel modifications, including the addition of a crane, mezzanine deck, and methanol tank. The revised stability assessment ensured continued compliance with applicable classification society and flag state requirements under the modified loading conditions.
Vessel Operability Analysis
Vessel — Havila Harmony
Scope — Detailed comparison of predicted vessel motions against recorded vessel motions captured during Vincent wellhead installation operations. The analysis validated the accuracy of the motion prediction model and provided key insights into vessel operability limits, response amplitude operators, and onboard location-specific acceleration levels under real offshore environmental conditions.
SPS Code Damage Stability Analysis
Vessel — CGG Symphony
Scope — Probabilistic damage stability analysis conducted in full accordance with SPS Code requirements, including assessment of all applicable damage cases and verification of compliance with survivability criteria. The analysis was submitted to and approved by DNV, ensuring the vessel met the necessary classification society standards for continued operation under the SPS framework.
Assessment of Stability with Crane Operations
Vessel — Nor Australis
Scope — Comprehensive review of existing vessel stability documentation with specific focus on crane operations, including assessment of free-surface effects, load distribution, and allowable lift envelopes. The project delivered updated recommendations for safe crane operations and vessel loading conditions to ensure continued compliance with applicable stability requirements.
Assessment of Vessel Stability for AH Operations
Vessel — Lady Sandra
Scope — Stability assessment carried out for six anchor handling tug (AHT) vessels in accordance with NMD anchor handling stability guidelines, conducted in the wake of the Bourbon Dolphin accident. The study evaluated each vessel's stability performance under anchor handling load conditions and provided recommendations to ensure full compliance with the updated regulatory requirements.
Offshore Engineering Projects
BRL's offshore engineering team delivers specialist analysis and design support across a broad range of marine and offshore projects, drawing on deep technical expertise in dynamic systems, mooring, and offshore operations.
Jack Up Site Specific Assessment
Vessel — Santa Fe
Scope — Site specific assessment carried out in accordance with SNAME T&R 5-5A guidelines, covering preload capacity, bearing failure, sliding, and overturning checks for the proposed jack-up location. The assessment was prepared and submitted to Bureau Veritas for review and approval, ensuring the unit's fitness for purpose at the designated site.
MODU Prelaid Mooring Design
Vessel — Jack Bates
Scope — Full design of a prelaid mooring system complete with synthetic rope inserts for the MODU Jack Bates, commissioned by Hess NWS Exploration. The design encompassed mooring line configuration, component selection, anchor positioning, and load analysis to ensure safe station-keeping performance at the designated offshore location.
Tank Transport Engineering
Vessel — Go Enif / Labroy 256
Scope — Comprehensive engineering and tow planning for the marine transport of two 35-metre diameter fuel oil tanks from Bell Bay, Tasmania to Newcastle, NSW. The scope included sea-fastening design, structural assessment of the cargo support arrangement, tow route analysis, and preparation of the marine warranty documentation required for the operation.
Crane Barge Analysis
Vessel — AMS Gladstone
Scope — Design of barge mooring system and crane mats and fastenings, along with determination of crane operating limits and dynamic amplification factors (DAFs) for crane barge operations on the Brisbane Riverwalk replacement project. The analysis ensured safe and efficient lift operations within the defined environmental and structural constraints.
Lift Engineering
Scope — Lift engineering services for pre-assembled units and loading arms required for the construction of the Woodside Pluto LNG jetty. The scope covered detailed lift studies, rigging arrangements, centre of gravity calculations, and dynamic load assessments to ensure all lifts were executed safely and in compliance with applicable engineering standards.
Gorgon LNG Jetty Caisson Barge – Mooring
Vessel — Boa 33 / Pacific Wrangler
Scope — Detailed mooring system design for the offloading of caissons from a semi-submersible barge at the Gorgon LNG jetty construction site. The work encompassed mooring line configuration, anchor positioning, load analysis under site-specific environmental conditions, and verification of the system's capacity to safely manage the offloading operation.
Towed Body Simulation
Vessel — Fugro Equator
Scope — Tow cable load analysis covering geometry and dynamic behaviour when towing a towfish sensor on up to 9.5 km of fibre optic umbilical. The simulation assessed cable tensions, catenary shape, and dynamic response under varying vessel speeds and sea states to ensure safe and reliable sensor deployment throughout the survey operation.
Vessel Mobilisation
Vessel — Normand Clough
Scope — Sea fastening design for the mobilisation of a field abandonment spread onto the Normand Clough vessel in support of the Lufeng 22-1 field abandonment project. The scope included structural assessment of deck loadings, fastening arrangement design, and preparation of the relevant engineering documentation to support safe offshore mobilisation.
Structural Design & Analysis
BRL delivers rigorous structural design and analysis services across marine, offshore, and industrial sectors, applying advanced finite element methods and engineering judgement to assess, design, and verify structural systems.
Shiploader Sea Fastening
Vessel — Happy Buccaneer
Scope — Structural engineering for the sea fastening of the Abbot Point X50 shiploader during marine transport from Brisbane to Abbot Point onboard the heavy lift vessel Happy Buccaneer. The scope covered sea fastening arrangement design, structural load calculations, and preparation of engineering drawings and documentation to support safe cargo transport.
