Marine Materials
Marine Paint for Boats: Topside vs Bottom Coating Systems
Separate topside weathering finishes from underwater barrier and fouling-control systems, with coating failure modes, a film-build example and repaint cost factors.

Marine Materials
Marine Cathodic Protection: Anodes, Impressed Current and Coating Limits
How sacrificial anodes and impressed current protect submerged marine steel, why barrier coatings still need cathodic protection, and how overvoltage causes blistering.

Offshore Wind
Floating vs Fixed Offshore Wind: What Changes Below the Turbine?
Compare fixed and floating offshore wind supports, moorings, dynamic cables and maintenance, including why platform type changes the tow-to-port option.
How Offshore Wind Farms Work: From Rotor to Onshore Grid
Follow offshore wind power from spinning blades to the onshore grid, with component roles and the cable differences between fixed and floating turbines.
Does Tidal Energy Harm the Environment?
Tidal harm claims depend on barrage or turbine, construction or operation, and one device or a large array. A 2025 review, a 2024 OES chapter, a 2011 NOAA memo and a 2009 paper differ in scope.
How Efficient Is Tidal Power? Read the Ratio First
A high tidal figure fails as a comparison until you name its denominator. Separate conversion efficiency, power coefficient, capacity factor and predictability.
Why Wave Energy Is Not Widely Used: Testing and Operations
A U.S. wave resource figure does not mean wave power is widely used. Separate the resource, a prototype, open-water tests, and a system crews can maintain.
Wave Energy vs Tidal Energy: Motion, Predictability and Resource Figures
How wave energy, tidal streams and tidal range differ in what moves, how predictable they are, and what U.S. terawatt-hour figures actually measure.
Marine Paint for Metal: How Coating Systems Protect Steel at Sea
Why marine paint for metal works as a system: what each coat does, how ISO 12944 grades sea environments and durability, antifouling versus anticorrosion, and surface prep.
Offshore vs Onshore Wind: Costs, Output and Trade-offs Compared
Offshore and onshore wind compared on one basis: capacity factor, cost per MWh, maintenance at sea, siting distance and depth, and the main concerns raised about each.
Wave Energy Explained: How Ocean Waves Become Electricity
How wind builds waves, how to estimate the power in a wave with the deep-water formula, the eight main converter types and what the U.S. resource figures mean.
