The KG of the DEEP DRILLER increases from 57 feet to 59 feet while drilling at a 60 foot draft during an ice storm. What action should be taken?

🔍 Key Concepts

• KG and stability relationship (higher KG = lower stability) • How removing high weight vs. shifting ballast affects KG • Use of the stability booklet/allowable KG curve at a given draft

💭 Think About

• Which options will actually lower KG at the same or safer draft, and which will raise KG even more? • In an ice storm, where is the added weight located, and how does that location affect KG and stability? • If you are already above the allowable KG, is it acceptable to keep operating while waiting for conditions to change on their own?

✅ Before You Answer

• Identify which choice directly reduces high vertical weight contributing to the higher KG • Check whether deballasting (pumping out low weight) raises or lowers KG at this draft • Confirm which actions are required when the rig is outside the allowable KG envelope per its stability manual, before considering notifications to authorities
