Work History

RENEWABLES

Marex carried out a review of all documentation for the installation of the topsides of the DolWin Alpha Offshore HVDC Platform, with operational recommendations for involvement by all stakeholders.

SAFETY CASE DEVELOPMENT

Over the last decade Marex has compiled well over 100 safety cases for mobile offshore units. Cases have been developed for semi-submersibles ranging from some nearly 30 years old, to new rigs under construction in the Far East. Safety cases have also been compiled, and approvals achieved, for drill ships, jack-ups and monohulls, including well intervention ships and one of the first DP accommodation vessels to enter service.

The work has consisted of qualitative and quantitative major hazard risk assessments, safety management system summaries and the inclusion of technical details, as well as the development of complete workplace and PFEER Assessments. Safety cases have been developed using a variety of templates including the IADC International Safety Case format, the IADC North West European Safety Case format, or client specific formats. Regardless of which format has been used, all safety cases presented for UK HSE "acceptance" since 2006 have been developed in accordance with the 2005 Offshore Installations (Safety Case) Regulations. Prior to that date safety cases were presented in accordance with the requirements of the Offshore Installations (Safety Case) Regulations 1992.

Thorough Review

Five yearly Thorough Reviews of Safety Cases are regularly being carried out by Marex for Drilling Contractors worldwide.

Major Accident Hazard Risk Assessments

These have also been undertaken, and safety cases written for mobile units operating outwith the UK regulatory regime, whose owners’ never-the-less wish to maintain high standards of safety and to assure their clients of the same.

EMERGENCY RESPONSE MANUALS

Based on the company’s detailed knowledge of offshore risks, Marex has been engaged to write many Emergency Response Manuals for mobile units. The work has included the development of realistic and operable Station Bills.

In accordance with the UK PFEER (Prevention of Fire and Explosion and Emergency Response) Regulations, these documents are provided with instructions, guidance, flowcharts and checklists.

VERIFICATION SCHEMES

In response to the requirements of PFEER and DCR (the Design and Construction Regulations), Marex have developed verification schemes and performance standards for jack-ups, semi-submersibles and DP mobile units and has put in place more than 20 schemes on behalf of clients.

In conjunction with this activity, Marex consultants have advised on maintenance requirements for SCEs (Safety Critical Elements) and have consulted with ICPs (Independent and Competent Persons) on behalf of their clients.

SHIPBOARD OIL POLLUTION EMERGENCY PLANS

Technical authoring activities have included the development of many Shipboard Oil Pollution Emergency Plans (SOPEP), also SMPEP’s and Emergency Response Manuals (ERM) in accordance with the relevant IMO guidance.

BALLAST WATER MANAGEMENT PLANS

Marex Marine Services have developed numerous Ballast Water Management Plans (BWMP) for new builds, and vessels currently in service, including the necessary stability calculations. Each Ballast Water Management Plan is written to Class standard for appropriate approval.

MOBILE UNIT MARINE OPERATIONS MANUALS

Marine Operations Manuals have been written for many units in accordance with client’s requirements and in their templates.

Where necessary, conformance with the 1989 MODU Code has been achieved. In addition Marex has advised on Stability Manual changes as a result of modification or lightship increases, in association with the revised Operations Manuals.

COMBINED OPERATIONS NOTIFICATIONS

When they were required by the Safety Case Regulations Marex participated in the development of, or managed the compilation of, a number of Combined Operations Safety Cases, and latterly Combined Operations Notifications.

These involved acting as a focal point for the collection of data from the participating companies, carrying out combined operations risk assessments, developing dropped object studies and compiling the documents in a form acceptable to the clients, and finally the HSE.

It is since the inception of the 2005 Offshore Installations (Safety Case) Regulations, that Marex has assisted its clients with the development of Combined Operations Notifications, and in addition has ensured that the Safety Cases contain the appropriate combined operations information.

RISK ASSESSMENT FACILITATING

The Company has provided facilitators for risk assessments other than those required to identify major accidents for safety case purposes. A number of processes have been used, including Bow-Tie presentations and the knowledge based HAZOPs.

Risk assessments carried out have ranged from assessments of the activities relating to the maintenance of stacked units, to the processes used to bring offshore units back into service after events and accidents.

    TRAINING

    The Company has developed a number of short training courses on instruction from its clients. These include:

    The Operation of Support Vessels at Offshore Installations

    This is a one day course describing the manner in which offshore support vessels are operated. There is a section on the operation of platform ships and one on anchor-handling activities from the point of view of those on board the vessels. The objective of the course is to familiarize personnel without a marine background, but who work at the interface on board offshore installations, with the strengths and limitations of offshore support vessels.

    Familiarization with the Safety Case and its Supporting Documents

    It is a legal requirement within the UK offshore regulatory regime that the workforce on board offshore installations be familiarized with the scope and content of their safety case. In addition there are rig owners elsewhere in the world who have developed safety cases or their equivalent, and also wish to ensure that their employees are appraised of the efforts that have been made to ensure their safety. Hence MAREX have developed and presented such courses for its clients.

    In addition to the safety case courses for offshore personnel, Marex has also developed a one day course for management to familiarize them with the requirements of the UK Safety Case legislation, and the requirements of the supporting statutes, the Design and Construction Regulations (DCR) and the Prevention or Fire and Explosion and Emergency Response Regulations (PFEER).

    Emergency Response Training

    It is essential that the operators of offshore installations, whether fixed or mobile, have the systems and personnel available to deal with any foreseeable emergencies. In order to ensure that these capabilities are in place and effective, Marex has provided advice and assistance, and has written training scenarios to test the procedures, systems and personnel, and where necessary has provided role players.

    TECHNICAL AUTHORING

    Because of its marine expertise and its in house authoring capability MAREX has carried out numerous technical authoring tasks outwith its normal activities. These have included:

    An IT Operations Manual and Handbook

    The revision of Operator’s Marine Procedures Manuals (from several original sources), including MODUs and FPSOs

    The Provision of Cargo System Operating Procedures/checklists and cargo record, log books.
