Safety Engineering Services
The design, operation & refurbishment of passenger ships and offshore vessels requires an integrated approach to safety engineering and risk management to demonstrate compliance with regulatory requirements & promote safety cultures and awareness.
Brookes Bell’s Naval Architects, Safety Consultants, Mathematicians & Software Engineers draw experience from a wide range of high-hazard industries, including oil and gas, marine, nuclear & rail, and hence are able to provide a comprehensive range of safety services.
Increasingly, there is a need to optimise cost, safety and through life performance by utilising alternative approaches & designs, nowhere is this more evident than for passenger ships where designs continue to push the boundaries of innovation for onboard comfort and entertainment.
Safe Return to Port
Brookes Bell are world leaders in the implementation of SOLAS Safe Return to Port (SRtP) requirements for passenger vessels. Developed in house, our sophisticated two stage approach evaluates the redundancy of essential ship systems, in accordance with SOLAS provisions and IMO guidelines, and provides a means for the owners & crew to demonstrate compliance, manage & monitor SRtP drills.
During vessel design our in-house Systems Analysis Modeller (BBSAM) is used to perform detailed & systematic FMEA/FMECA evaluations on behalf of ship designers and builders. The output from BBSAM forms the basis for developing the required documentation for Flag approval and provides the input to Brookes Bell’s onboard Crew Advisory System (BBCAS). BBCAS then assists the ship emergency organisation by defining the appropriate crew instructions needed to recover essential ship systems for a specific damage scenario.
Advanced Evacuation Analysis & LSA Assessment
Brookes Bell’s Naval Architects & Safety Consultants have provided advice & guidance on LSA and evacuation arrangements on over 40 vessels, typically in support of new designs, design iterations or changes, fire risk assessments, changes in passenger numbers or crew manning levels, & validation of passenger terminal turnaround times.
Our team use Brookes Bell’s in-house evacuation software EVI [which conforms to the definition of advanced evacuation analysis in IMO MSC\Circ.1533 & SOLAS Chapter II-2 Regulation 13-7.4] to carry out advanced evacuation analysis.
Using the software our team are able to quickly verify the effectiveness & performance of planned escape routes, muster/embarkation stations & LSA arrangements, as well as identify and eliminate potential congestion points. Ownership & experience with our own software also means we can customise the software to cater for specific Client requirements & propose design changes to improve evacuation arrangements.
Alternative Design Assessments (ADA)
Brookes Bell Safety at Sea has accumulated significant experience in the assessment of alternative design and arrangements in accordance with the provisions of SOLAS and the respective IMO guidelines. Our expertise in design risk analysis, operational ship safety and ability to undertake engineering analysis in a multitude of disciplines allows us to provide efficient and robust input to the design team, when evaluating deviations from prescriptive requirements on behalf of ship designers, builders, owners or equipment manufacturers.
Fire Risk Screening
Fire screening and explosion risk assessments on passenger ships & offshore vessels can be undertaken during the concept and design stages to identify major accident (dimensioning) events and verify the suitability of proposed fire safety provisions & fire fighting equipment.
Brookes Bell employs fire risk screening methods developed in-house for assessing proposed layouts against performance criteria & the requirements of FSS code and UK PFEER regulations. Fire Dynamics Simulator (FDS) CFD software is used to carry out fire engineering and tenability calculations.
FMEA & FMECA Analysis
Brookes Bell’s Safety Consultants have extensive experience in FMEA/FMECA reliability & safety assessments of key operational & safety systems on board passenger ships and offshore vessels.
FMEA or FMECA is used as a means of determining the integrity of a system by analysing the effects of individual component or subsystem failures. Whether as a desktop exercise or multi-day group workshop, Brookes Bell offer a tailored approach that ensures an appropriate level of detail is employed for the maturity of the available design information to deliver a comprehensive and efficient assessment.
For very complex, high dependency or critical systems, Brookes Bell utilises our in-house Systems Analysis Modeller (BBSAM) which can be used to create a full inter-system dependency model of essential systems, which includes the geographical location of components. The software can be used for FMEA analysis, assess the effects of common cause failures or damage scenarios and highlight system weaknesses.
Vessel Manning & Muster Lists
By drawing on the experience of our Master Mariners & Marine Engineers we are also able to assess minimum safe manning levels for normal vessel operations & emergency scenarios.
We employ specialist inhouse software to identify the individual tasks & dependencies associated with normal operations & emergency scenarios. Tasks are assessed to determine manning levels and crew competencies, in accordance with a vessel’s safe manning certificate and the Standards of Training, Certification and Watchkeeping for Seafarers (STCW).
The software outputs vessel specific muster lists & emergency action cards for common emergency scenarios, which make the most efficient use of crew onboard whilst accounting for manning levels needed for emergency work parties, operation & launch of LSA and importantly passenger safety, control & reassurance.
Offshore Safety Services
In addition to Safety Services common to both passenger ships & offshore vessels, Brookes Bell provides offshore specific safety assessments to check compliance with statutory, Class or relevant national regulations, such as UK HSE, PFEER, NORSOK and NOPSEMA.
Our Safety Consultants are experienced in EEA & EERA studies, which typically cover definition of major accidents & dimensioning events, alarm & detection, egress & access, temporary refuge, evacuation, escape & rescue arrangements.
Using our in-house CFD capability, we can carry out helicopter operability analysis to check for CAP 437 compliance. Complex geometries of offshore rigs & FPSO’s can be rapidly constructed allowing assessment of wind turbulence and temperature changes on the landing platform for true & apparent wind angles.
Qualitative & quantitative approaches are used by Brookes Bell for dropped object assessments. We focus on implementation of design and operational rules to reduce or eliminate the frequency of dropped objects and where necessary adopt probabilistic assessments of the likelihood of impact and engineering analysis of the consequences.
