A Global Perspective on Marine Shock Mitigation
A challenge for the builders of next generation RIBs and high speed craft is delivering platforms that balance high performance with the physical demands on crew and passengers.
When taking a holistic approach to reducing injury, operators need to consider lessons learned by other sectors including coxswain training, managing time and speed expectations for different vessels and improved passage planning.
EU and UK Vibration Directives recognise that fast boats can be a high risk means of transport. RS & WBV (Repeated Shock & Whole Body Vibration) can be damaging to helmsman, boat crew and their passengers. Acute and chronic injuries from operating at speed in waves include lower back and knee injuries.
The definition of shock mitigation is, 'to make a violent collision or impact less intense'. A shock mitigation strategy is essential for all craft that undertake open sea transits or operate in rough water. This includes rivers and estuaries with wind against tide conditions which form short, steep waves.
With the arrival of ‘unbreakable boats’ plus a surplus of engine power ‘man’ is often considered the weakest link. In recent years, academia and industry focus has mainly been on developing mechanical suspension seats to reduce the effects of vertical accelerations when seated.
Hard decks can be an issue when people stand in one place. Even with high performance seating installed, people need to walk around the vessel to carry out onboard tasks or to embark. To reduce fatigue, cushion decking materials can also be used when leaning posts or jockey style seating have feet on deck.
Other areas requiring attention include fore-aft, lateral and vector forces, plus improving seat cushion performance and comfort for lower speed vessels. In 2019 the NEXT GEN Shock Mitigation Solutions Workshop examined how groups around the world are taking different approaches to solving these problems - and how these efforts can be utilized by organisations to reduce the risk of injury for people working on and around boats.
RS & WBV Training
Specialist training for professional operators of RIBs and High Speed Craft is essential for organisations affected by the EC Vibration Directive.
Repetitive Shock (RS) and Whole Body Vibration (WBV) training courses are relevant to all designers, builders and operators of planing vessels under 24 metres (80 feet).
