De Beers Marine - Subsea Excavation Tool and Topside Equipment

Market: Subsea Diamond Mining Year: 2005 This project entailed the design, manufacture, installation and commissioning of several major systems for the flagship diamond mining vessel, mv Peace in Africa – recently renamed mv Mafuto. This included the subsea crawler, launch and recovery and four point mooring systems.

Crawler The mining crawler was the primary mining element of this project with the function of providing a mobile dredging tool to deliver product to a surface processing plant. The major functional areas of the design were: tracks, a pivoting boom assembly, a suction system consisting of a variable speed 2432 kilowatt (kW) motor coupled to a dredge pump, thrusters to control tool orientation during launch and recovery, a hydraulic system powered by a HPU comprising a 500 kW motor and pumps, electronic system with an array of sensor equipment and the tool lubrication system.

Mooring

To ensure that the vessel remains in position above the crawler during mining, a four-point mooring system was necessary. The system consists of four 100Te line pull mooring winches, four fairleaders, bend sheaves and line tension meters. The mooring and LARS equipment were classed/certified according to the Lloyds Register of Shipping.

De Beers Marine - mv Coral Sea Mooring Winch

Market: Subsea Diamond Mining Year: 2007 This project entailed the design, manufacture, installation and commissioning of the starboard aft mooring winch, tower assembly, deck bend sheave and fairleader on the mv Coral Sea vessel. Control and instrumentation was also a part of the scope. The winch stores 1900m of wire rope and weighs over 47 tonnes; it is powered by three hydraulic motors. As part of an overall life extension project on the mooring system, IHC MMP is currently managing the fabrication of a replacement for the port aft mooring winch and aforementioned ancillary structures.

Subsea 7 - Air Dive Handling System

Market: Oil and Gas (Air Dive Support) Year: 2007 This project entailed the design, manufacture, installation and commissioning an air dive handling system for the purpose of delivering support to divers and ancillary equipment to 50m water depths. The system, which was classed/certified according to the Lloyds Register of Shipping, included:

A diver hoop boom system for launch and recovery of a diver’s hoop to prevent divers from being pulled towards the thrusters of the vessel;

A dive basket deployment system with associated clump weights for dive basket guidance and emergency recovery;

A triple drum winch system for product (air, hydraulics and welding cable) storage, deployment and recovery; and

De Beers Marine - Sampling Tool and LARS Modifications

Market: Offshore Mining and Exploration Year: 2009 De Beers Marine (DBM) procured a Launch and Recovery System (LARS) for the new subsea sampling and ground truthing tool from New Zealand Diving and Salvage. The LARS was designed to be installed onto a charter vessel but was never commissioned due to various technical problems being experienced with the sampling tool. DBM contracted MMP to assist with a review of the existing LARS design, design the required modifications and produce detailed drawings for the modifications to be implemented in New Zealand prior to fitting the LARS to the proposed charter vessel.

Mertech - Bow Roller

Market: Submarine Cable Recovery Year: 2010 Mertech Marine had an existing cable recovery guide roller assembly on the bow of the mv Lida. The unit, however, was not effective as it has encountered problems during cable recovery. The design of an alternative solution was requested of IHC MMP. The proposed solution – which was subsequently fabricated and installed – consisted of a powered bow roller and support structure to assist with the recovery of cable, taking into consideration the minimum bend radius of the cable, through a magnitude of recovery angles.

IHC Mining - IHC SWORD Seafloor Sampling Tool

Market: Deep-sea Mining and Exploration Year: 2012-2016 Mining operations are by their nature founded on the existence and understanding of the mineral resources. Exploration, identification and development of mineral resources are fundamental to the existence of any mine. Whilst subsea geophysical data acquisition methods have improved hugely over the past few years, subsea geotechnical data acquisition (specifically sampling) has not seen the same level of advancement. SWORD The project entailed a background study, concept and high-level design of a new generation seafloor sampling tool for core sampling. The Sonic Wireline-Operated Remote Drill (SWORD) is the solution developed by IHC MMP. The IHC SWORD is capable of providing class A samples (4 inch), up to 50m ground penetration, fully cased, at a depth of 2000m. The SWORD and associated LARS is completely modular, capable of fitting into standard offshore containers, for quick mobilization and demobilization.

Rendering of Deployed SWORD

The IHC SWORD project has subsequently developed into an implementation phase, whereby IHC MMP is currently finalizing the detail design and executing manufacturing activities, leading up to final assembly and Factory Acceptance Testing.

Containerised Winch

The positive reception of the SWORD lead to a secondary project entailing the investigation of winch containerisation. Increasing the modularity of the system will enable swift deployment and improve redeployment turn-around times in case the client were to require the SWORD to transfer between multiple vessels.

Turkuaz Machinery - Excavator Trailing Cable Reelers

Marker: Open-pit Mining Year: 2013 - 2016 The Excavator Trailing Cable Reeler is designed to handle and store the supply cable providing electrical power to large open-cast mining excavators, such as the Hitachi EX3600. The Cable Reeler safeguards the power cable extending from beneath the excavator by maintaining a constant tension in the cable. This eliminates the risk of the cable becoming tangled, being driven over by the excavator and of the excavator travelling beyond the limits of the length of cable which is wound on the Cable Reeler. The Cable Reeler is designed to be permanently cantilever-mounted to the structure between the tracks of the excavator. IHC MMP has successfully manufactured and supplied seven units for Turkuaz Machinery to be used for a mining operation in Eastern Europe. IHC MMP also provided installation supervision and commissioning services on-site.
