HMS Protector and the cost of a hard polar service life

What has happened to the Royal Navy's icebreaker HMS Protector?

Expensive engine trouble and accumulated polar-service wear are suspected. Replacement is considered reasonable after roughly 25 years of total service, and the ship is described as already included in replacement planning.

Protector is described as a commercially built ship acquired for polar research and icebreaking after an earlier Norwegian career. Originally a temporary replacement for HMS Endurance, she has reached roughly 25 years of total service in the age comparison used here. Engine trouble is suggested as the explanation for the missed deployment, with the cause remaining an inference. Repeated Arctic and Antarctic service is expected to shorten useful life compared with cruising in milder conditions. Replacement is therefore considered reasonable, and the ship is described as already included in replacement planning. Finland and Russia provide examples of rolling icebreaker replacement programmes. Heavily used off-road vehicles offer a comparison for why exceptional survivors should not determine normal life expectations. Replacing a ship's machinery costs much more than repairing an old vehicle, while failure at sea carries different consequences.
