Seaspan Cavalier Repower: Long Life, Big Hours
“We got 59,115 hours on those engines, without ever removing a head,” says Seaspan International’s Port Engineer Kevin Tweedy, “And they were still running. So, at 5,000 to 5,500 hours per year, we could easily have done 60,000 hours.”But the company schedule worked to do a like-for-like repower. The pair of 850-horsepower Tier 1 Cummins KTA38 diesels were pulled out, and a brand-new set of 850-horsepower Tier 2 KTA38s went in.The Seaspan Cavalier was built in 1974, along with three sister ships.
US Coast Guard Surf Boats: Service Life Extension
Since the days of wooden hulls and human power, lifeboat crews have put to sea through dangerous surf to save the lives of their fellow seamen.
