Among the equipment included in the DEEP DRILLER lightweight are the loading hoses, derrick, traveling block in the lowest position, anchors, all machinery with liquids to normal operating level, and __________.
• Lightweight displacement definition for offshore drilling units (what is always on board, not used up in service) • Difference between permanent equipment and variable loads/consumables (fuel, food, temporary gear) • Items that are part of the unit’s original construction and fixed equipment versus what can change from voyage to voyage
• Which of these items would still be there in exactly the same amount on the day the rig is built, before any operations, fuel loading, or crew provisioning? • Which options look more like consumables or operational gear that can be added, removed, used up, or varied depending on the job, rather than being part of the basic rig? • Lightweight already includes anchors and machinery with liquids at normal operating level—what type of item matches that same "built‑in, permanent" character among the choices?
• Identify which options are consumable or variable (can be used up or changed regularly) and rule them out for lightweight. • Check which option would be considered permanently installed or part of the rig’s structure/equipment rather than cargo or provisions. • Ask whether each item must be included to get an accurate, repeatable lightweight value in the stability booklet, or if it belongs under variable load instead.
