2 How We Work MAREX is renowned for its ability to succeed with all missions entrusted to its staff: Reliability, Timeliness of work, Quality of work Safety of its own teams and its clients, teams, Confidentiality. In MAREX Subsea Welds Ltd, we take the Client's needs seriously. That's why, before we start on site operations, we proceed to a demonstration of the work method statement and of the result we will produce, when projects involve Coded Welding & N.D.T. Inspections. Specializing in Custom-Made Solutions We cover every phase: Identification of needs, Feasibility studies, Virtual 3D modelling and animation, Turnkey solutions and Maintenance. Depending on project requirements, we can design and manufacture any construction required which can make the course of the projectsuccessful. QHSE Our target is the commitment to Health and Safety and Quality Management. Ongoing reviews, internal auditing, inspection, communication, and training of personnel combined to ensure that safety and quality standards are monitored and continuously improved. This requirement is in place to effectively manage the evolving challenges provided by the global marine construction working environment. MAREX is supported by a multi-skilled and professional workforce, equipped to provide turnkey solutions for maritime and inland over or under water construction projects. ABS Quality Evaluation ISO 9001 Marex is approved for its management system by ABS for the following topics: Coded Hyperbaric Welding Services (Dry & Wet) Development & Approval of Welding Procedures Underwater Welder Training for Commercial Divers (the WeldCraft-Pro) Manufacturing & Supply of Diving and Welding Equipment The Passion and Ambition for overcoming Major Challenges MAREX has been meeting challenges for over 20 years, on the basis of a simple and precise logic: To any problem raised by a client: - We find the solution - We design and produce the solution - We implement the solution with highly professional teams that focus on safety and quality.

3 Development and Approval of Welding Procedures Marex Subsea Welds Ltd participated in Underwater Wet Welding Trials on Examination and Testing of Barracuda Gold Electrodes and specific Evaluation of mechanical & weld quality properties in Accordance with AWS D3.6:2010, Class A (Comparable properties and testing requirements with above water welding). The purpose of this investigation was to identify if underwater wet-welding could now be performed, using the electrode Barracuda Gold, to deliver weld metal quality in accordance with AWS D3.6M: 2010 Class A, therefore moving this process out of temporary to permanent repair methodologies. Under the AWS D3.6M underwater welding specification Class A welds are intended to be suitable for applications and design stresses that are comparable to their conventional surface welding counterparts, by virtue of specifying comparable properties and testing requirements. For the purposes of these trails, welding was conducted at -3M water depth in a freshwater training tank. Water temperature was 7C⁰ and visibility was good. All welding was performed by Mr. George Maroudas. From the evidence supported in the report (More info: utilising careful control for welding operations and attention to detail, the evidence from the NDT and destructive examination and testing has shown that class A wet welds has been achieved.

4 ABS Academy Marex is a Certified Maritime Training Center Marex is a Training Center that provides education and training services to the global Marine Industry. One of the courses provided by the company is WeldCraft-Pro whose objective is to allow a Commercial Diver to become competent in Underwater MMA/SMAW Coded welding. Marex is approved by the ABS Academy for Maritime and Offshore related education, training facilities and of the courses it provides. Marex Subsea Welds is approved as/for: Training Center WeldCraft-Pro Course

5 Underwater Welder Training This course is fully certified by EAL, part of SEMTA Sector Skills Council for Science, Engineering and Manufacturing Technologies, the UK s leading awarding body for engineering qualifications. The course is also recognized by IMarEST The Institute of Marine Engineering, Science & Technology. The training is based on an 80 hour programme, split over two phases, covering both dry and wet welding and is open to both non-welders and welders alike. All training follows the International Institute of Welding (IIW) and European Welding Federation (EWF) syllabus for fillet welder plate and cover the following topics; Safe underwater welding Introduction to MMA Welding plant & equipment Underwater welding techniques Preparing to weld Electrode & weld terminology Basic Weldability & common weld defects Monitoring & record welding operations QA/QC and welding procedures Join carbon steel plates using standard techniques Training is designed to provide commercial divers with the competencies in both theory and practice of underwater manual metal arc (MMA) welding. Welder approval qualifications are conducted is accordance with the following welding standards: BSEN ISO , AWS D and BS 4872.
