WHY MARINE
CONTRACTORS
RUN OUT OF CASH.
Marine contractors run out of cash because of three structural pressures that do not exist in other trades. Massive upfront mobilization (often $200K to $1M to position barges, cranes, and floating equipment). Weather-dependent production windows that compress revenue into narrow periods. And milestone billing structures that delay cash recovery on the costliest phases of work. Without systems built specifically for these patterns, marine contractors burn through cash before the first major billing milestone hits. Even when the projects are highly profitable on paper.
Marine has more in common with heavy civil than with most other commercial trades. With its own complications layered on top. Weather. Salt environment equipment degradation. Environmental compliance costs. Water access. CONTROL handles all of it.
Massive Upfront Mobilization
Positioning a barge, crane, or floating equipment package for a commercial marine project can run $200K to $1M before any production work starts. If mobilization is buried in unit pricing instead of its own billable SOV line, the contractor floats that cash for 60 to 90 days. On a $5M project that is enough cash strain to break a $15M business.
Weather-Dependent Production Windows
Marine production happens during weather windows. Outside those windows, equipment sits idle but ownership costs (lease, insurance, depreciation, maintenance reserve) continue. Without an equipment cost basis built around realistic utilization across the full year, idle time invisibly bleeds margin.
Milestone Billing Delays Cash Recovery
Commercial marine projects often bill on completion milestones (piles set, demo complete, dredging certified) rather than monthly progress. The biggest costs hit first. The biggest billings hit last. Without a 13-week cash forecast built around the specific milestone schedule, payroll crunches show up where they should not.
Salvage and Equipment Replacement Reserves
Salt environment shortens equipment life. Floating equipment is specialized. Replacement is not a commodity purchase. Most marine contractors do not carry adequate replacement reserves in their cost basis. When the inevitable major equipment expense hits, it lands as a crisis instead of a planned outflow.
On a $25M commercial marine GC we worked with, the financial picture was invisible at the project level. Four accounting staff. No job costing. No per-project reporting. Healthy projects were subsidizing losing projects with nobody able to tell which was which. The business was profitable in aggregate. It could not make any meaningful decisions about which work to pursue and which to walk away from.
On a $13.5M commercial marine GC, the business was running at 7 percent net profit when 14 percent was achievable. The 7-point gap was almost entirely a function of equipment cost basis errors and mobilization recovery problems. Neither was visible without proper job costing.
- Chapter 1, Job Cost Structure: 7-category framework with project-level visibility. You can see which projects, which clients, and which work types are actually profitable.
- Chapter 2, Equipment Cost Basis: true cost basis on barges, cranes, dredges, and specialized equipment. Accounts for realistic utilization, salt environment maintenance, and replacement reserves.
- Chapter 4, Estimating Alignment: SOV structuring that puts mobilization in its own billable line. Recoverable on application one rather than buried in unit pricing.
- Chapter 6, PM Standards: billing on the contract milestone schedule. Change order discipline for environmental conditions. Notice of nonpayment when GCs slow-pay.
- Chapter 7, Monthly Cadence: 13-week cash forecast built around the specific milestone billing schedule of each active project. Not a generic monthly assumption.
Two of the CONTROL case studies are commercial marine contractors. One went from 7 to 14 percent net profit in 9 months ($2.3M valuation lift). The other built the entire financial infrastructure from scratch on a $25M business and paid out $2.6M in profit sharing.
WANT IT INSTALLED FOR YOU?
CONTROL teaches you how to build the system yourself. The Construction CFO, a service of Sulphur Prairie Management, builds and runs it for you. Same system. Same outcomes. From $1,900 per month. 60-day onboarding.
Marine work has three structural cash flow pressures. Massive upfront mobilization. Weather-dependent production windows that compress revenue into narrow periods. And milestone billing structures that delay cash recovery on the costliest phases of work. Without systems built for these patterns, marine contractors burn through cash before the first major payment milestone hits.
Typical commercial marine mobilization runs $200K to $1M depending on the equipment package and water access. That cash leaves the business before any meaningful billing happens. If mobilization is buried in unit pricing instead of billed as its own SOV line item, the contractor floats it for 60 to 90 days. On a $5M marine project that is enough to bankrupt a $15M business.
Marine work has weather windows. Periods when conditions allow production. Outside those windows, equipment sits idle but ownership costs continue. Without an equipment cost basis built around realistic utilization, idle time is invisibly bleeding overhead. The CONTROL equipment cost basis methodology calculates true cost across actual utilization, not theoretical.
Generally no. Marine has specialized patterns that generic CFOs miss. Barge day rates. Crane positioning costs. Weather-dependent productivity adjustments. Environmental compliance billing. Salvage value on specialized equipment. Sulphur Prairie Management has installed CONTROL with two commercial marine contractors. The patterns repeat.
10 to 14 percent net profit is healthy for commercial marine. Most run 5 to 8 percent because the structural cash and overhead problems eat margin invisibly. With CONTROL installed properly, marine contractors regularly reach the 12 to 14 percent range. One $13.5M case study went from 7 percent to 14 percent in 9 months on the same revenue.
