Maritime and Naval
Modern seafaring vessels come in many shapes and sizes. Modern carriers can carry over 10,000 containers, cruise ships can carry thousands of guests, and supertankers can carry millions of barrels.
The vessels have unique requirements for crew and cargo safety, depending on the ship classification. The increased size and complexity of modern vessels results in long design, certification, and service cycles. Therefore, reliability assessments during the design process are crucial for optimal product design, reducing cost, risk, and time to market.
High level maintenance tasks and overhauls require procurement of Long Lead Items (LLIs). Failure to prepare in time may cause long spare waiting times and reduced fleet availability.
Low level maintenance tasks have to be conducted while at sea, therefore the ship has to be self-sufficient. This requires a careful choice of Carry On Board (COB) spare parts and support equipment.
COB is critical for mission reliability of naval ships.
Another issue is obsolescence. Since vessels have very long lifecycles, spare parts may become unavailable. Planning for obsolescence may include buying spare parts in advance (depending on equipment shelf life), looking for substitute items, and preparing for equipment upgrades.
